Hmmm, that's a most interesting view!
Still, I would very much like to hear you opinion on my suggestion for a
way out of the "loophole" conflict; namely, allow the default setting of
the of :adjustable argument to MAKE-ARRAY to be implementation-dependent.
That way, we could maintain portability on what the :adjustable argument
means (i.e. NIL means "Not Adjustable"). Symbolics' users would likely
have no code broken, since the Symbolics default setting would be just
be :adjustable = T. (Does any user *ever* explicitly supply a NIL for
this argument?).
